Outcome in the real-world of coronary high-risk intervention with drug-eluting stents (ORCHID) -- a single-center study comparing Cypher sirolimus-eluting with Taxus paclitaxel-eluting stents.

We present real world experience from a single center registry comparing the 6-month outcome of percutaneous coronary intervention (PCI) in unselected high-risk individuals using either sirolimus-eluting (SES) or paclitaxel-eluting stents (PES). We compared clinical outcome at 6 months follow-up in two cohorts of 156 consecutive patients (total n = 312) who underwent SES (June 2002-February 2003) and PES (march 2003-July 2003) implantation. The primary endpoint was a composite of major adverse cardiac events (MACE). Baseline clinical characteristics were well matched. The 6-month target vessel revascularization (TVR) rates were 1.9% (SES) and 2.6% (PES) and MACE rates were similar in the two groups (SES 4.5% vs. PES 3.2%, P = NS). In the PES group, intervention for multivessel disease, bifurcation lesions and in small vessels was more common, and for in-stent restenosis less common, reflecting the impact of drug eluting stents on indications for PCI. The incidence of sub-acute stent thrombosis, related to inadequate antiplatelet therapy in 3 of the 6 cases, was 0.95% with no difference between the two groups. This study confirms the safety and efficacy of SES and PES in unselected high risk patients undergoing PCI. Clinical outcomes of both stents are equivalent at 6 months with low rates of MACE and TVR. These data provide important complementary information to forthcoming randomized studies.

Four-year clinical outcome of sirolimus- and paclitaxel-eluting stents compared to bare-metal stents for the percutaneous treatment of stable coronary artery disease.

There are limited data on the long-term safety and efficacy profile of coronary stent implantation in patients with stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). We aimed to assess the 4-year clinical outcome in patients who received a bare-metal stent (BMS), sirolimus-eluting stent (SES), or a paclitaxel-eluting stent (PES) for the percutaneous treatment of stable angina in our center during 2000-2005. In the study period, a total of 2,449 consecutive patients (BMS = 1,005; SES = 373; and PES = 1071) underwent a PCI as part of three historical PCI-cohorts for stable angina and were routinely followed for the occurrence of major adverse cardiac events (MACE). At 4 years follow-up, 264 BMS patients (26.8%) had a MACE, compared to 75 SES patients (20.9%) and 199 PES patients (23.9%). Multivariate analysis showed that SES and PES were superior to BMS with respect to MACE [hazard ratio (HR) = 0.62, 95% confidence interval (CI): 0.47-0.81; HR = 0.67, 95% CI: 0.55-0.82, respectively]. The occurrence of MACE was significantly lower in the SES and PES population, primarily due to less target-vessel revascularization (TVR) procedures (HR = 0.53, 95% CI: 0.37-0.75; HR = 0.71, 95% CI: 0.62-0.81, respectively). The occurrence of early, late, and very late stent thrombosis was equally rare with each stent type. There were no significant differences between SES and PES on death, myocardial infarction, TVR, and MACE. These findings suggest that SES and PES result in decreased TVR procedures and MACE compared to BMS at 4 years follow-up. SES or PES implantation should be the preferred choice over BMS for patients with stable CAD undergoing PCI.
